摘要 目的观察不同经皮冠状动脉介入(PCI)时间对老年急性心肌梗死(AMI)患者恶性心律失常发生的影响。方法因AMI而接受PCI的老年患者依据发病至接受PCI时间分为观察组(≤6 h)86例及对照组(>6 h)92例。结果观察组术后心律失常累积发生率显著低于对照组(χ~2=7.869,P=0.005)。治疗后24 h,两组丙二醛(MDA)及超敏C反应蛋白(hs-CRP)水平均较治疗前显著升高(P<0.05),而超氧化物歧化酶(SOD)水平显著下降(P<0.05)。观察组术后MDA及hs-CRP显著低于对照组,而SOD水平显著高于对照组(P<0.05)。受试者工作特征(ROC)曲线分析显示,以6 h为截点值,PCI时间预测AMI患者PCI术后恶性心律失常发生的敏感性为88.89%,特异性为70.42%,曲线下面积为0.79。结论不同PCI时间对老年AMI术后恶性心律失常发生具有重要影响。
